BAND-CUITERAND FEEDER FOR CORN SHREDDERS AND HUSKERS.

SPECIFICATION forming part of Letters Patent No. 733,275, dated July'7', 1903.

Application filed January 23,1903. Serial No. 140,317- (No model.)

To all whom it may concern.-

Be it known that I, NATHANIEL G. ROBIN- SON, a citizen of the UnitedStates, residing at WVoolstock, in the county of \Vright and State ofIowa, have invented a new and useful Improved Band-Cutter and Feeder forCorn Shredders and Huskers, of which the following is a specification.

My object is to provide a simple, strong, durable, and efficientband-cutter and feeder specially adapted for feeding bundles of corn tobrushing-rollers and a shredder-cylinder.

My invention consists in the construction, arrangement, and combinationof parts as hereinafter set forth,pointed out in my claims, andillustrated in the accompanying drawings, in which- Figure 1 is a topView, from which the roof of the frame and case is omitted. Fig. 2 is aside elevation of my machine, that shows the positions of the differentoperative elements relative to each other and the frame and case withwhich they are connected. Fig. 3 is a diagrammatical View of a blankadapted for making a bandcutter complete from one piece to be fixed tothe cutter-shaft to 006perate with an endless carrier to advance bundlesto the cylinder of a threshing-machine or cornstalk-shredder.

The numeral 10 designates the frame, 12 a fixed double inclined bottom,and 13 a fixed roof on the frame. A crank shaft 14 is mounted inbearings fixed to the rear corneruprights of the frame, and a pluralityof rakebars 15 are pivotally connected with the cranks of the shaft attheir central portions and with the frame at their rear ends by means oflinks 16. A cutter-shaft l7is mounted in bearings fixed to the top andrear portion of the frame 13. A plurality of cutters of peculiar shape,each made from a single piece of sheet steel or blank, (shown in Fig.3,) are fixed to the cutter-shaft 17. Each cutter has a circular centralportion 18 and wings 19 and 20, that project in reverse ways relative tothe axis of the shaft 17 and incline laterally relative to their centralportions and are arranged relative to each other, as shown in Fig. 1, sothat the two central ones will extend longitudinally at right angles tothose fixed to the end portions of the shaft. The peculiar shape of theblank produces a curved cutting edge a, that extends from the outer endof one of the end portions of the complete cutter into the central partof the other end portion of the complete cutter and is inclinedlaterally to the center of the complete cutter.

By the peculiar form of the cutters having wings inclined laterally totheir center porti ons they are specially adapted to serve asband-cutters and feeders and spreaders of bundles and to cooperate withthe rake-bars 15 in separating and advancing advantageously the stalksto the cylinder of a thresher or shredder-machine. The curved eccentriccutting edges are thus very materially lengthened without extendingtheir outer ends relative to the shaft to which they are fixed.

A jointed and foldable conveyor-frame 22 is connected with the rearuprights of the frame 13, and 23 is an endless carrier mounted in theframe and adapted to be connected with the cutter-shaft 17 by means ofwheels and belts, as hereinafter set forth.

An endless carrier 24 is mounted on the double inclined bottom 12 andconnected with the cutter-shaft by means of fixed pulleys and a belt.

To transmit power from the cylinder-shaft of a thresher orshredder-machine, a bandwheel 25 is fixed on one end of the cuttershaft17 for connecting the cutter-shaft with the cylinder-shaft in a commonway by means of an endless belt.

To transmit power from the cutter-shaft 17 to the crank-shaft 14, aband-wheel 26 is fixed to the cutter-shaft and a corresponding wheel 27to the crank-shaft and applying a belt on said wheels.

To transmit power from the crank-shaft 14: to the shaft 28 of theendless carriage 23, a belt-wheel 29 is fixed to said crank-shaft and acorresponding wheel 30 to the carrier-shaft 28 for a belt adapted to beplaced on said wheels.

To transmit power from the shaft 31 to the endless carrier 24, a shaft31 is mounted at the upper end of the double inclined bottom 12 in aplane below the shaft 28, as shown in Fig. 2, and provided with abelt-wheel 32 and the corresponding wheel fixed on the end of the shaft28 to be connected by means of a belt. (Not shown.)

Having thus described the purpose of my invention and the construction,arrangement, and combination of all the elements and subcombinations,its practical operation and utility will be understood by personsfamiliar with the art to which it pertains, and

What I claim as new, and desire to secure by Letters Patent, is

1. In a band-cutter and feeder, a cutter formed from a single piece ofsheet-steel consisting of a circular central portion adapted to be fixedto a shaft, wings projecting outward and laterally from thecircumference of said central portion in opposite directions and curvedcutting edges extending from the outer end of one end portion of thecomplete cutter into the central portion of the other end portion, asshown and described for the purposes stated.

2. In a band-cutter and feeder, a rotatable shaft, a plurality ofcutters, each consisting of a circular central portion having wingsprojecting laterally in opposite directions from its circular center anda curved cutting edge extending from the outer end of each end portionof the complete cutter into the central portion of the other end portionof the complete cutter, fixed to the shaft in rightangled positions arelative to each other, as shown and described for the purposes stated.

3. An improved band-cutter and feeder comprising a rotatable shaftmounted on the top and front end of a suitable frame, a plurality ofcutters, consisting of circular central portions and wings projectinglaterally from the circumference of the central portion, fixed to theshaft in right-angled positions relative to each other, a crank-shaft ina plane below the said cutters, rakes pivotally connected with thecranks of said shaft at their central portions and pivotally connectedat their lower ends with the frame of the machine by means of links, adouble inclined bottom fixed to the frame in a plane below the saidrakes and an endless carrier mounted on said bottom, a jointedconveyer-frame hinged to the machine-frame and an endless carriermounted on the conveyer-frame, arranged and combined to operate in themanner set forth for the purposes stated.
